BUTTON-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 649,929, dated May 22, 1900.

Application filed April 19, 1899. Serial No. 713,551. (No model.)

To aZZ 207L072), it 'nmconcern;

Be it known that I, GEORGE XV. GWINN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have in vented certain new and useful Improvements in Button-Setting Machines, of which the following is a specification.

' This invention relates to an improvement in button-settin g machines. to The object of the invention is to provide a chuck that will hold the fastener while the plunger is making its preliminary stroke and release the said fastener before the plunger has completed its stroke, thereby allowing the i5 fabric to be gripped tightly between the button and the head of the fastener and held by the points of the said fastener.

In devices heretofore used for attaching buttons to garments the ordinary button with a bar across the center could not be rigidly secured to the fabric, as the means for holding the fastener in position prevented the fabric from being gripped tightly between the button and the head of the fastener.

The invention is illustrated in the accompanying drawings, in whioh- Figure 1 is a side elevation of a machine having my improved chuck, the lower part of the machine being broken away. Fig. 2 is a 0 plan view of the chuck, the jaws being shown in the open position by dotted lines. Fig. 3 is a vertical section of the chuck and part of the plunger, showing the position of the parts as the clencher comes in contact with the points of the fastener. Fig. LlS a similar view showing the position of the parts when the plunger has made its final stroke, the tapered pin having entered the hole and forced the jaws apart, the fabric being gripped tightly between the button and the head of the fastener, and the points of the fastener curled around the bar of the button.

Similar figures of reference are employed to denote corresponding parts in each of the figures, respectively.

1 designates the base of the chuck, 2 the jaws, and 3 the plates carried by the said jaws. The said base 1 is made of one piece of metal and at the front projects upward to form an anvil on which. the fastener rests. The

as shown in Fig. 2. jaw 2 is a plate 3, which extends out to the base 1 is provided with a post hwhich [its into the semicircular grooves 5 of the jaws 2 when the latter are closed together and serves to hold them in their proper relative position. At the rear the base 1 is provided with a hole 6, in which the bolt 7 is inserted. This bolt 7 serves to support the rearend of the chuck against any strain caused by the separating of the jaws 2. The head of the bolt 7 rests on the base of the machine, as shown in Fig. 1.

The jaws 2 are secured to the base 1 by screws 8 or other suitable means, which form the pivots on which the said jaws turn when spread apart. The rear ends of the jaws 2 are beveled to permit them to be spread apart,

At the front end of each front end of the base 1. These plates 3 are each provided with a cut-out 9, as shown in Fig. 2, through which the points of the fas- 7c toner 24 project when the latter is in position to secure the button to the fabric. As shown, these plates are made of separate pieces and are secured to the jaws 2 by means of screws 10; but they may be made integral with the said jaws. The jaws 2 are also provided with semicircular grooves 11, which when in the closed position form a hole through which the pin 17 works to spread the jaws. The jaws are held in the closed position by the spring 13. Each of the jaws 2 has an upright 14:, the edges of which abut when the jaws are in the closed position, as shown in Fig. 2. These uprights are attached to the jaws by screws 10 and form a guide to regulate the distance the buttons are to be set from the edge of the fabric to which they are to be secured.

The plunger 15 of the machine carries a clencher 16, which latter is magnetized and serves as the means for holding the button 27. go The plunger 15 also carries a tapered pin 17, which serves to spread the jaws 2 apart when the said plunger is brought down, the said pin entering the hole formed by the semicircular grooves 11, spreading the said jaws apart, and extending down into the hole 18 in the base 1, as shown in Fig. at. The said plunger is operated by means of a treadle (not shown) connected to the lower end of the rod 19, the bell-crank lever 20, and links 2]., 22, and 23; too

but any other suitable means may be employed to operate the same, this forming no part of my present invention.

a The chuck is secured to the base of the machine by the bolt 25, which projects through the said base and is held thereto by a nut. (Not shown.) In the present instance I have shown a two-prong fastener; but it is obvious any other suitable fastener may be used.

To secure the button, the operation is as follows: The button is placed against the ..clencher 16, which latter is magnetized and olds the button thereto. The fastener is placed in position between the base 1 and the plates 3, the head of the fastener resting on said base 1 and the points projecting upward between the two plates 3. The fabric 26 is then placed in position, as shown in Fig. 3. The plunger 15 is now brought down, which also carries with it the button 27 and tapered pin 17. As the crimper comes in contact with the points of the fastener the point of the said tapered pin projects slightly into the hole formed by the semicircular grooves 11, as shown in Fig. 3. As the plunger is making its final stroke the jaws 2 are forced apart by the tapered pin 17 entering the hole formed between the said jaws by the semicircular grooves 11, thereby removing the plates 3 from between the fabric and the head of the fastener, thereby allowing the cloth to be gripped tightly between the button and the head of the fastener and held by means of the points of the fastener curled around the bar of the button, as shown in Fig. 4. Thus the button will be rigidly secured to the cloth. When the treadle is released, the plunger will return to its normal position, carrying with it the pin 17, and thereby allowing the jaws 2 to be closed again by means of the spring 13.

If it is desired to secure the button flexibly to the fabric, this can be done by regulating the stroke of the plunger by means of the nuts 28, which may be set to allow the plunger to come down only far enough to give the points of the fastener a slight curl around the bar of the button.

Having thus described my invention, what I claim is l 1. In a button-setting machine, the combi= nation of a stationary base, 1; two jaws, 2, pivoted to said base; a plunger, 15; a pin, 17, carried by the said plunger, which pin serves to separate the jaws when the plunger makes its traverse downward; means for holding the button to the plunger; and a spring, 13, to close the jaws after the fastener has been re leased.

2. In a button-setting machine, the combination of a stationary base, 1; two jaws, 2, pivoted to said base; a plunger, 15; means for holding the button to theplunger; a pin, 17 carried by the said plunger, the said pin serving to force the jaws apart after the points of the fastener have been slightly curled around the bar of the button, thereby allowing the fabric to be tightly gripped between the head of the fastener and button; and a spring, 13, to close the jaws after the button has been secured to the fabric. 4

In testimony whereof I affix my signature in the presence of two Witnesses.
